Victoria Beckham celebrated her 40th birthday in a bikini sprawled next to her shirtless hubby David Beckham. It may be safe to declare them the hottest couple in Hollywood.

The former Spice Girl tweeted the cozy photo on Thursday. "Having a wonderful day with my family x vb," she wrote. The pic shows her in a red, white and black striped bikini top that barely seemed to cover her breasts. Meanwhile, Becks showed off his toned, tatted chest as he smiled for the camera.

"[He] is the most wonderful man I have ever met," she gushed about David in last month's Allure magazine. "He's a fantastic father. He's incredibly talented, a wonderful husband. I supported him for many years and he's proud of me. He supports me. We're very equal at home."

She posted another shot of herself on Instagram wearing what looked to be lingerie. In the pic, Posh stood in the sunshine with her back to the camera as she outstretched her arms. The gorgeous family is vacationing in Utah; they hiked to the Grand Canyon earlier in the day.

The usually private designer also shared several childhood snapshots yesterday.
